To ALI. wPIoM In MAY coNcERN;

Be it known that I, GASPAR HUNZIKEB, of Summit, in the county of-Pike,and State of Mississippi, have invented a new and improved Apparatus for Distillng Wood, irc.; und I-,do hereby declare that the foliowng's .Y

e full, clear, and exact description thereof, which will enable others skilled in'tb'c nrt to makeand use the same, reference being had to the accompanying drawings, formingpart of this Specification.

This invention relates to a new and improved method of constructingapparatusfor distilling wood and stonecoal, whereby the resin and tar contained inthe sameare more effectuullyseparatedifrom the` charcoal or carbon, and whereby the same is more' economically done.- I

It consists of en oven made oi" boiler-iron or other suitable material,"pr'o vded at one end with suitable furnaces, and provided also with suitable steam and air-pipes; provided also on the inside with n railway-track and carriages, bymeans of which the wood or other substance to be distilled-1s conveniently conveyed into the i oven. Said oven is provided also, in'the'bottom of the same, with a gutter or trough by means of which the tar and resin are carried from the oven into some suithble receptacle for the same. In the accompanying plate of drawingsg Figure 1 represents an end view of my invention.

Figure 2 is a. central vertical section of the same, taken Ain the line :c cv, fig. 3.

Figure 3 i5 a vertical section of the salme, taken in the line y y, iig.

A is the oven; K are the furnaces Fare the ues S is the chimney; T isa-dpme'openingin'to the oven A; o is a pipe connected with said dome T, opening into the air', d are pipes in the oven A, opening into the air; C are the carriages, shown as loeded vwith wood eare the rails on bottom of oven A, on which carriages C run; e are carriage-wheels of carriages C;v mure the Vhot-fair chambers; G is a gutter or trouvh in the oven A; W

is the outlet of gutter G; At are steam-pipes for edmitting'steam to oven A g h are air-pipes .for admitting air to oven A; y are cold-hir pipes; Yl is the door; Y an air-tube through the oven A. The oven Aie made of boileriron, or other suitable material,rectangular in form, covered with a metallic roof, highestiin the middle. The bottom of suid'oven A is raised or rounded at the lo\vcr`corners, and has in the middle of the same a gutter or trough, G, running the whole length, so constructed ns to be lowest at the `opening W of the same, as shown in the drawing.l nto the lower end of said gutter G, as shown, is a pipe or opening, W, provided with a. suitable stop-cock, by means o? which the tar distilled from the wood is carried o. Upon euch side ofthe cutter G are the hot-nir chambers M, formed by the rounded corners of the oven, and covered' by the plates aa.s show n in the drawing, 3. Above the-plates, and attached to .the inside of the oven A,a,s shown, are the plates a', inclined in like manner with the' plates a, as shown in the drawing, the object being' to retain the heet from the furnaces K, and give direction to the same under thctmiddle of the wood contained in the carriages C. Upon the plates-a are thc vertical strips e extending from one end 'of' the oven A to the other, and` parallel to each other, soas to form a support for the carriages C, andait* theI Sametime form rails upon which-thewheels e' of the carriages C run. Upon one end of the oven A, and near the bottom ofthe same, us shown in the drawings, gs. 1 und 2, are the furnaces K. Said furnaces K are made -iu the ordinaryway,'eachsaid'furnce K having fines F, which said ues F, commencing at the furnaces K, run-underthechumbers M the Wholle` length of the oven A; then turning upwards, they continue along thewhole length 'of the ovento'the furnace-end ofthe oven A again, inclining'fromthe bottom to the top ofthe oven, whenthcyluute in a-chimney,.`S.

In the end of the furnace A, opposite to the furnaces K, and beneath the door P, are two or more steami pipes, t, for the admission of steam to the oven. In the same end of the oven A with the furnaces K, and directly over the same, .are the air-pipes k, opening into .the oven A,'so as to supply nir to the chambers M, said ppost and h being provdcdavith suitable Astop-cock, to shut ott' the communication through the same to tho oven A.

In the `same end of the oven' A as the furnaces K, and over and between said furnaces, are suitable air-pipes, l

2 y, running entirely through said oven A from endI to end, and along the outside of ther gutter G, by means ot which said'gutter G is kept cool. Upon the oven A, and opening into the same, is a dome or condenser, T, by means of whichthe vapors arising from the distilling'wood are condensed. I

Through the top of the oven A is anyconvenient number of pipes, d, provided with suitable stop-cocks, as shown in the drawing, for the escape of smoke and gas. Upon the top 'of thevoven A, and opening into the The carriages C, which may be of any. convenient number, are rectangularfshaped boxes, formed of-strips or slats of wire, of sufficient size nearly to ll theoven A'.' Said carriages C are provided with wheels, upon which said carriages run`.upon the rails on the strips e, in such a way that they may easily at any time run in or ont ofthe oven A. :The ovenA is provided atthel end opposite to the furnaces K with a door, P, ot` nearly-the size of the end of the oven A, so that the opening of said end may be tightlyclosed-whenthe o'venis in use. The

carriages C are provided at' one end with a door, by meansof which the charcoal-may. be easily removed. Said door P is attached to the bottom ofthe oven A, by suitable hinges, so that the said door P may swing outwards' and downwards. Said door'P is provided upon the upper orpinner side with rails so' constructed 'as to be n.

K continuation'of the rails e, so as to form skids upon which the carriages may be run into and outof the oven.

Theopcration is such-that the carriages C, being` filled with wood or stone-.Coah are run into the oven, when the door P is closed, and made tig and keep up an equal and uniform heat, a thermometer being placed in -any convenient place, so that the amount of heat may be easily ascertained.

This may be continued as long as necessary, when thc steam s 'shut oft at the steam-pipes t, and a small remaining in the carriages C, which may then be `rolled out and their contents discharged. The operation-wav be repeated as Aoiten as required.

Constructed as above described, it constitutesl a cheap and durable apparatus, by means of which the tar or resin contained .in wood and'stone-coal-may he easily distilledfromthe same, and collected yin any convenient receptacle for the same, leaving the charcoal in the carriages', from which tmay easily be taken, thev advantages being that the msi" 01' 'tm' may be more eectually separated from the wood, leaving the charcoal behind without' loss or waste. f v

I claim as new, and desire to secure by Letters Patenti v 1. The oven A, constructed as described, havingthe rounded lower edges,'and the central longitudinal inclined trough G, whose inclined wings, a, support the vertical strips and rails e for the carriages C, the inclined v plates a', above the wings'a, the cold-air pipes y, beneath said inclined wings, and between the tlues F,'the top of said oven provided with the condensing-dome T, all arranged as described, for the purposespecified,A

2. The arrangement of the furnaces K, inclined iucs F, trough G, c ol -air pipes 3], draught-pipes L, steampipes t, hot-air chambers M, and carriage-supporting rails c, as herein described, for the purpose specified. p 3. The door P, provided with a track upon its inner` side, whereby, whe'u it is swung-down in a horizontal position, it receives the carriages C, which are rolled out upon.it to discharge'thcir loads, as herein shown and described.

4. The furnace-dues F, wheuarranged to pass beneath the curved bottom of the oven A, upon eachl side of 'the projecting trough G, and,- curving outward, extend in an inclined direction` upon each side of said oven to the front thereof over the furnaces, to unite in the chimney S, as herein described, for the purpose specified.
